Europe's Coldest Cities in Summer. Europe's northernmost city has the continent's coolest summers. No other major city stays anywhere as tepid as ReykjavÃ­k, Iceland, where maximum temperatures average a meagre 12.7 degrees Celsius (54.8 degrees Fahrenheit). That's over five degrees Celsius (10 Â°F) lower than the next coldest city, Leeds.
The seasons: spring and summer. In spring (February to April), the average highest temperatures range from 46 to 54Â°F, with April considered particularly pleasant. In summer (May to July), the averages for highest temperatures are between 64 and 68Â°F.The warmest months, July and August, get about 18 hours of daylight and it gets dark only after 11pm. Hence the well-worn phrase in Ireland; sure there's a grand stretch in the evenings.reland's climate is influenced most by the Atlantic Ocean. As a result, it doesnât have the extreme temperatures that other countries at similar latitude would have. The average temperature is a mild 50Â°F. A major warm ocean current called the North Atlantic Drift keeps sea temperatures mild too.
